What the job involves on each surface

Bathrooms and en suites

En suite seals are easy to miss on a snagging list until they leak. Resealing properly keeps water where it belongs.

Kitchens

New-kitchen sealant is often applied in a rush. We take it out and reseal neatly, colour-matched where it shows.

New build mastic for homes and businesses in Bishopton

A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. If you’re dealing with internal frame sealant that has split and kitchen sealant that has pulled off the wall, we can help.

New homes in smaller Scottish places are often single plots, self-builds or small developments. They need their sealant and floor joints finished just as carefully as on a big site.

Your job is guaranteed for a year, as with all our work.

Signs you need new build mastic in Bishopton

Sealant is often one of the last jobs before handover. Joints aren’t always cleaned of dust or primed, so the bead never bonds properly.

If you can see any of these, it’s time to have the joints looked at:

  • Sealant work across a run of new homes
  • Beads laid onto grit and dust from the build
  • Cracks appearing as a new home settles
  • Gaps behind new kitchen upstands

If you’ve bought a new home near Bishopton station, the sealant around baths, showers and frames is worth checking in the first year or two.

Choosing a sealant specialist

How the visit works

We keep the work tidy and contained to the joints we’re treating, so you can get on with your day. Expect the work to take a few hours in a single home, and we tell you how long to leave it before we go. Outside jobs in Bishopton need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.

  1. We start by going through the snagging items or plot schedule with you.
  2. Every bit of the old builder’s sealant is cut out.
  3. We clean out the dust and grit left from the build.
  4. We prime where needed and apply a sealant suited to each joint.
  5. Each bead is tooled and the cure times explained.

How to prepare

  • Let us know if you’ve seen damp or leaks
  • Clear items away from the joints we’re working on
  • Let us know about earlier repairs to the joints

In hotels, rooms out of use cost money, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.

Joints and finishes in Bishopton homes

Bishopton is within about 1 mile of the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. The west of Scotland is wetter than the east, which means plot mastic and the sealant in new homes has to cope with a lot of rain.

In and around Bishopton, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Your questions about new build mastic in Bishopton

I let a flat near Bishopton station. Can you help?

Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.

Do you cover smaller places like Bishopton?

Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

My new home is still under warranty. Should I contact you?

Your builder, if you are still in their snagging or warranty period. After that, or if their repair keeps failing, we can do it with our 12-month guarantee.

Do you take on second-fix sealing for builders?

Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send the schedule and any specification and we will give you a quote.

Why has my new-build shower seal failed already?

New homes dry out and move in their first couple of years, and sealant is often applied quickly onto dusty surfaces. Either can make it fail early.

What does new build mastic cost?

Size, access and the old material all affect the cost. Ask us for a quote and we’ll talk you through it.

Will you leave a mess?

Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we are done.

Are you insured?

Yes. We are fully insured for domestic and commercial work.

Looking after it afterwards

Aftercare is simple:

  • Wipe joints with warm soapy water
  • Check bath and shower seals every few months as the house settles
  • Put sealant faults on your snagging list early
  • Open a window or run the fan after bathing

Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it as they wear the bead.

If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.

Should I try it myself first?

If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
